As usual, you can then run "port outdated" to see the set of outdated ports and "sudo port upgrade outdated" to upgrade them. However since it has been well over a year since you last updated you may run into some problems. [...]
As a data point I run "port -u uninstall" every Sunday to clean out old (i.e. saved) ports, then "port selfupdate" every Monday and follow my nose from there. There is no specific reason for that timing; it's just how the care and feeding of MacPorts through osmosis worked out over time...
As an aside, my own MacPorts is semi-trashed due to Migration Assistant refusing to bring MacPorts from the old MacBook to a newer Pro, so I stupidly(?) decided to do it by hand instead of starting from scratch; as a result I'm now hung up on finding a suitable Xcode for the Pro with Sierra 10.12.6 and seeing all sorts of conflicting advice.
Hint: don't believe the answers on StackOverflow; its mission in life appears to be to mislead newbies...
